IPython Magic Functions

ipython-magic's Issues

Could you make ipython-magic available via PyPI?

Dear Chris,

could you please make ipython-magic available via PyPI?
So far, I have been able to use it via IPython's %install_ext magic, but that is no longer available.

Best regards,
Arne

'Dot' object has no attribute 'encode'

I'm trying to make one of your extensions work (completely new to IPython, first notebook, first code I'm writing in python)... It's going well, trying to plot strings, like one would expect, but I'm not sure how to make objects plottable... I'm getting this error:

AttributeError: 'Dot' object has no attribute 'encode'

For code on the instance fig6, like:

    def to_dot(self, Args=set()):
        if type(Args) is not set:
            Args = set(Args)

        try:
            graph = pydot.Dot()
        except NameError:
            print("Not able to import pydot. This functionality will not work.")
            return

        for arg in self._Ar:
            graph.add_node(pydot.Node(str(arg), shape='circle'))

        for attack in self._df:
            graph.add_edge(pydot.Edge(str(attack.attacker), str(attack.attacked)))

        for arg in Args:
            graph.get_node(str(arg)).pop().set_shape('doublecircle')

        return graph

With requirements.txt:

Since I'm so new at this, I don't really know how to continue...?

PS, also getting. Is this normal?

  "as a python packages.", UserWarning)

Doesn't work with Jupyter

My version 6.1.0, and when I try to %load_ext gvmagic, I get the error message 'ImportError: No module named 'IPython.utils.warn''
